As for the subdungeon ideas - just adding the 5 pieces of convertible junk to any of the new subdungeons would do.

If a new one is added they could even make it the Packmaster subdungeon

Or you could even have a goblin Miner guarding a set of 5 defused goblin mines (pallete swap to blue, and make them give 15/20 CP as opposed to 25 and have no other functionality whatsoever). I'd like it as a standard subdungeon if the tileset matched whatever the place you were in, as if the Goblin acidentaly mined into there

Bumping this for still thinking it's an idea that merits a week or moth of trying out. Ick Swamp gives out so much junk it's unbelievable and mostly doesn't fit in your inventory (and if you DO somehow fit it in your inventory - you get stupidly powerfull). If conversion pact was viable, and the strat worked anywhere, it would rock socks in the current Ick Swamp (and myabe allready does if you can come up with the piety somehow - the current required 50 piety for 100 CP isn't such a hot deal, except maaaaybe for goblins*.

Conversion pact could really use some love. And plants could drop conversion fodder instead of spoons. And I did find a bunch of "nice conversion" or "3 random items" subdungeons around the place but would still love a "5 useless items with mediocre but nice total conversion" one that could spawn anywhere.

*Which is why if they ever let us test this out, Goblins are something that will need a bunch of testing conisdering the crazy stuff that can happen if you let them go silly with conversions. Assasins and Fighters in particular.
